Sketch a velocity-time graph with negative acceleration and give an example for such a motion.
Answer to Problem 1Q
An object ejected from earth’s surface is an example for such a motion and the graph has been drawn.
Explanation of Solution
An object escapes from Earth’s surface to space with a high initial velocity will have the velocity is always positive, but the acceleration is always negative. Eventually the velocity will diminish resulting in negative acceleration. The velocity will never be zero in such cases.
The sketch for such a motion is given in figure 1.
Conclusion:
An object ejected from earth’s surface is an example for such a motion and the graph has been drawn.

- I am having trouble with an average speed problem. The problem states that a person walks at 4.5 meters per second from point a to b. Then walks back from point b to a at a speed of 3.2 m/s. I know that average speed is displacement/time. However I am not sure how to calculate time or displacement from the two givens. The problem also gives that the average velocity is 0.arrow_forwardsketch a position vs time graph and a velocity vs time graph and an acceleration vs time graph. At time t = 0 you are walking in the positive x direction with a constant speed of 1 m/s. You maintain that speed for 6 s. Then, you decrease your speed uniformly to 0 over a 2 s interval. You rest for 2 s, then turn around and increase your speed uniformly to 2 m/s in 2 s. You continue at that speed until you return to the starting place.arrow_forwardConstruct a graph of instantaneous velocity versus time for a motion with variable acceleration.
